In a competitive market, maintaining health care quality while containing costs requires that consumers and large purchasers of care have access to data on the cost and quality of care in health plans. Both individual health plans and more neutral bodies, such as the National Committee for Quality Assurance, have attempted to meet this demand for information by presenting plan-specific performance data in a “report card” format. Although the perspective of the consumer figures prominently in such reports, the perspectives of physicians, nurses, and other health professionals who deliver care are notably absent. Practicing health care providers are often the passive subjects of assessments of health plan quality; they may also implicitly express their opinions by, for example, deciding to stay with or leave a plan. However, providers seldom directly and systematically provide their perspective on the quality of the systems in which they practice. Formal assessment of providers' perspectives on quality in health plans may complement consumer surveys and other performance measures. We argue that these perspectives should be included in the assessment of the quality of health plans, and we discuss the association between provider satisfaction and providers' perspectives on quality of care.
